Please note that this section contains my personal notes from my readings on this topic.

From The Toxic Sandbox (2007) by Libby McDonald; pages 155 – 156:

From 1995 to 1999 Dr. Xiaomei Ma and a team of researchers studied the correlation between pesticide exposure and childhood leukemia in northern California. By interviewing the parents of eighty-one newly diagnosed kids, who ranged in age from birth to fourteen years, and comparing their family pesticide exposure with that of eighty-one healthy children, Dr. Ma was able to analyze the effects of pesticide usage during three key developmental periods: three months before pregnancy, during pregnancy, and each year after birth for three consecutive years. Dr. Ma found that children who have leukemia are twice as likely to have been exposed to pesticides applied by professional pest control services. The study also showed that risk of leukemia is significantly elevated if the application occurred when a child was in utero.
